The range of the Safed Koh flanks the Kurram valley and encloses the Kabul basin, which finds its outlet to the Indus through the Mohmand hills.
One of the chief centres of Rabbinism was Safed, still a sacred city of the Jews and largely inhabited by members of that faith.
The principal town is Safed, perched on a white mountain 2700 ft.
At this north-western angle (in 35° N., 74° E.) the mountains curve southwards, and India is separated by the well-marked ranges of the Safed Koh and Suliman from Afghanistan; and by a southern continuation of lower hills from Baluchistan.
As they proceed southwards, their best marked ranges are in turn known as the Safed Koh, the Suliman and the Hala mountains.
